$resource restful
As of Angular 1.2, resources support promises. But they didn't change the rest of the behavior.
To leverage promises with $resource, you need to use the $promise property on the returned value.
Example using promises
var Todo = $resource('/api/1/todo/:id');
Todo.get({id: 123}).$promise.then(function(todo) {
// success
$scope.todos = todos;
}, function(errResponse) {
// fail
});
Todo.query().$promise.then(function(todos) {
// success
$scope.todos = todos;
}, function(errResponse) {
// fail
});
Just keep in mind that the $promise property is a property on the same values it was returning above. So you can get weird:
These are equivalent
var todo = Todo.get({id: 123}, function() {
$scope.todo = todo;
});
Todo.get({id: 123}, function(todo) {
$scope.todo = todo;
});
Todo.get({id: 123}).$promise.then(function(todo) {
$scope.todo = todo;
});
var todo = Todo.get({id: 123});
todo.$promise.then(function() {
$scope.todo = todo;
});
